This protocol includes two questions. All participants aged 25 years or older are asked their current height (i.e., the first question). Participants 50 years of age or older are also asked their height at 25 years of age (i.e., the second question). If measured height is taken, it should be AFTER self-reported maximum adult height has been recorded.

Protocol

This protocol is part of a computer-assisted personal interview. The PhenX Anthropometrics Working Group recommended that this could also be used as a paper-and-pencil personal interview and may be a self-administered interview.

The following are the two questions for this protocol:
